Nathrae, also known as Tiff, is a Drow living in Underdark. She is first seen in Rugnar's Realm, wandering aimlessly and unresponsive, giving the impression that she has suffered severe trauma and is out of touch with reality. According to Rugnar, her mind has been damaged by a Mindflayer. He has taken her in out of pity, as both a companion and an assistant.
